Default storageclass volume missing

[ekandreas]

When i provision these scripts from scratch the k8s environment missing a default storageclass for automatic volume claim.
So when using a simple helm install like mysql it will be stucked on mounting a volume.
Any clue how to get pass that issue?

What I do is:

1. install isci
2. deploy openebs helm chart
3. Create openebs storage pool resource
4. Create openebs storageclass

Openebs docs can help with it.

I haven't got around to making a PR for this because it's part of a more elaborate deployment strategy but the strategy above does work nicely.

I haven't looked into local volumes but maybe that's a possibility too. https://kubernetes.io/docs/concepts/storage/storage-classes/#local

Another thing to note, is that with the DSSD volumes (C2L) instances, I observed much better performance. An additional step is required if using C2L local SSD which is to mount the DSSD local disk.

@stephenmoloney Do you have a blog post or other instructions on how to do this? Sounds very useful.
